"I can't figure it out "said the first dog.
"I'm in perfect shape, I run around all day getting lots of exercise. I eat well and sleep a lot but I'm always anxious."
"About what?" the other dog asked.
"I don't know the first dog said."
"Well, why don't you go to a psychiatrist?"
The first dog looked pained; "How can I? I'm not allowed on the couch!"
